We look at the division of 721783 by 48 
We want to figure out the number of times 721783 can be divided by 48.

Moving on to step 1:
The number 48 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 48

Moving on to step 2:
48 can be fit into 72 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 24 after subtracting 48 from 72.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 48

On to step 3:
48 can be fit into 241 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 1 after subtracting 240 from 241.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 48

On to step 4:
48 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 48

Let's proceed to step 5:
48 can be fit into 178 3 times, resulting in a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 1503.0
The remainder is 34 after subtracting 144 from 178.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 48

Going ahead to step 6:
When dividing 343 by 48, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 15037.0
If we take 336 away from 343, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 48 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 15037.1
Subtract 48 from 70 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
When dividing 220 by 48, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 15037.14
The remainder is 28 after subtracting 192 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 48 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 15037.145
Subtract 240 from 280 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 48, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 15037.1458
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 48, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 15037.14583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 15037.145833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 15037.145833 with a remaining 1.6e-06.
